... and not only when sort-of feeling like it.
In any case, if it turns out all really is in order,
and presumably DTS == PTS, then no ctts will be produced anyway.
We can't rely on audio sources pushing EOS when going PAUSED->READY
because this is a basesrc bahavior and when used inside autoaudiosrc
the ghostpad goes flushing before the real source pushes the EOS,
so it is dropped.
Audio elements are put into bin only when needed, so we need
to be careful with their states as camerabin2 won't manage
them if they are outside the bin.
Also we should reset their pad's flushing status before
starting a new capture.
Adds an audio source and audio capsfilter/queue/convert, creating
a new branch on camerabin2 that is used to feed encodebin with
audio buffers for video recording.
Adds properties to check what caps are supported on the
viewfinder (from the camerasrc viewfinder pad) and another
one to set a caps for the viewfinder.
Adds a virtual function to basecamerasrc in case subclasses want to be
notified of changing preview caps. This is useful if the subclass wants
to post the preview itself or if it wants to provide a preview buffer
as close to as possible to the user's requested resolution to the
preview generation pipeline.
Use video_renegotiate and image_renegotiate booleans to make
the videosrc negotiate the capture caps on the first capture because
the caps might be set before wrappercamerabinsrc goes into PLAYING
and pads drop the internal renegotiate event.
This is required as the output-selector is using the 'none' negotiation
mode.
When setting the internal capsfilter caps for capture we should put
the full caps instead of trying to fixate it ourselves. This way we let
the elements (and mostly the source) select the best format instead
of defaulting to what the pad fixation function picks.
Adds gst-camerabin2-test example application, similar to
gst-camerabin-test for camerabin.
It is useful for taking pictures and recording videos using
camerabin2 and providing arguments for most of camerabin2
properties
This element analyses video buffers to identify if they are progressive,
interlaced or telecined and outputs buffers with appropriate flags for a
downstream element (which will be the deinterlace element, after some
forthcoming modifications) to be able to output progressive frames and
adjust timestamps resulting in a progressive stream.
